An elastic thread foreskin ring tightening structure

Abstract

The invention belongs to the technical field of medical aids, in particular to an elastic thread foreskin loop tightening structure. It includes a collar, a clamping component arranged on the outside of the collar, and an elastic line component arranged on the clamping component; the collar is in the shape of a ring, and the outer wall of the collar is provided with an elastic line limit groove; the clamping component includes interlocking The carrying ring and the crimping ring are combined. There are card slots on the opposite surfaces of the carrying ring and the crimping ring. The upper and lower card slots are set opposite to each other and combined to form a bayonet; the elastic thread assembly includes a block, a buckle and an elastic coil The tightening structure of the elastic wire foreskin ring of the present invention is easy to use, and the position of the elastic coil can be effectively controlled through the mutual cooperation of the carrying ring and the pressing ring. The quasi-inner loop enables the elastic coil to be tightened accurately and quickly and ligated on the sleeve to complete the operation.

Description

technical field [0001] The invention belongs to the technical field of medical aids, in particular to an elastic thread foreskin ring tightening structure. Background technique [0002] The ligation device is suitable for all kinds of medical devices for internal and external ligation operations. The elastic thread ligation device has the characteristics of convenient and quick operation and low cost. At present, many types of elastic thread automatic ligation structures have appeared on the market, which can improve the operation efficiency. Reduce operation time. But on the other hand, the function and structure of the existing elastic thread ligation structure are relatively simple, and the operating process of elastic thread tightening mainly depends on the experience of the operator and the doctor.

Problems solved by technology

But on the other hand, the function and structure of the existing elastic thread ligation structure are relatively simple, and the operating process of elastic thread tightening mainly depends on the experience of the operator and the doctor. Since the elastic thread itself is soft, vibration and tilt during the operation are very difficult It is easy to cause deformation of the elastic thread, or make the elastic thread slip from the corresponding support structure. At the same time, the tightening process of the elastic thread is a dynamic operation. If the elastic thread is not tightened in a timely and accurate manner with the area to be ligated, it will easily lead to surgical failure. Or the effect becomes worse, which brings unnecessary pain to patients and limits the popularization and application of ligation technology.
